PK 13/14. By Plagron. 

There comes a point in every grow cycle when your plants start whispering, “Feed me more.” Not with nitrogen. Not with leafy green nonsense. No, this is the moment they want to pack on the weight, to turn those fledgling clusters into dense, fruit-laden powerhouses. Enter Plagron PK 13/14, the Dutch-engineered mineral weapon that’s been designed with one mission in mind: delivering the phosphorus and potassium your plants crave, right when it matters most.

A For Soil, Coco & Hydro. 

This isn’t some whimsical organic compost tea that relies on moon phases and miracles. Plagron PK 13/14 is a mineral-based formula - highly refined, immediately absorbable, and clinically precise. It’s made for growers who want measurable results, not guesses. And while it won’t make the cut for your organic certification paperwork, it more than makes up for it in raw performance. Whether you’re working with soil, coco, or full-scale hydro, this additive integrates seamlessly into your feed schedule and pushes results that are both visible and tangible.

Tighter Clusters. Denser Development

What sets Plagron PK 13/14 apart from the usual suspects in the bloom booster market is its potency at relatively low concentrations. Just 2ml per litre is enough to give your plants the push they need without triggering toxic salt build-up or creating runaway EC levels. It’s been engineered to stack on mass without compromising the delicate balance of your nutrient reservoir. Add it gradually as you enter peak flowering, and you’ll notice the difference. Tighter clusters, denser development, and a harvest that suddenly feels like it’s worth the effort you put in.

A Personal Trainer for Plants.

One of the quieter benefits of Plagron PK 13/14 is its synergy with other bloom-phase additives. Used in combination with Plagron Sugar Royal, the results are even more pronounced, with boosted photosynthesis, chlorophyll production, and accelerated metabolic activity. It’s a bit like giving your plants a personal trainer and a private chef at the same time. All you have to do is water them.

For Fast & Strong Growth. 

At the core of Plagron PK 13/14 is a precisely balanced 13% phosphorus and 14% potassium ratio, formulated to kick your plants into high gear during the flowering phase. Phosphorus lays down the structural framework of every flower and fruit - driving energy transfer, root growth, and the cell division that builds weight. Potassium, meanwhile, hardens the lot. It’s responsible for water regulation, enzyme activation, and most critically, increasing the density and quality of your fruit. When used correctly, Plagron PK 13/14 doesn’t just fill out your flowers - it reinforces them like scaffolding around a cathedral.

Solid Foundation for Large & Heavy Flowers.

Finally, there's the scalability. Plagron Terra Grow comes in four convenient sizes, meaning you’re not locked into a 1-litre trial bottle once you realise it’s actually doing what it says on the label. From small stealth grows to full-blown production facilities, the size options let you commit at your own pace. So, whether you're coaxing seedlings into adolescence or pumping out a forest of cuttings, Plagron Terra Grow lays down the solid vegetative foundations that every successful harvest is built on. And frankly, your plants deserve nothing less.
